vigra - 8-bit SBus color frame buffer with VGA-compatible
modes
vigra* at sbus? slot ? offset ?
wsdisplay* at vigra?
The Vigra VS10, VS11 and VS12 are 8 bit color frame buffers
with user-selectable
video modes, and a VGA-compatible connector.
The vigra driver interfaces the frame buffer with the wscons(4) console
framework. It does not provide direct device driver entry
points but
makes its functions available via the internal wsdisplay(4)
interface.
The video resolution and signal synchronization modes are
selected with
four dip switches on the back of the card.
VS10 and VS12 Switch Settings:
The VS10 and VS12 support the following basic modes:
